                         LIBBEY INC. GUARANTY AGREEMENT

      THIS GUARANTY AGREEMENT (as amended, revised, modified, supplemented or
amended and restated from time to time, this "Guaranty") is entered into as of
June 24, 2004 by LIBBEY INC., a Delaware corporation (the "Guarantor"), in favor
of BANK OF AMERICA, N.A., in its capacity as administrative agent for the
Lenders (as hereinafter defined), and the GUARANTEED CREDITORS (as defined on
Exhibit B attached hereto). All capitalized terms used but not otherwise defined
herein shall have the meaning ascribed to such term by the Credit Agreement (as
defined below).

                                   WITNESSETH:

      WHEREAS, Libbey Glass Inc., a Delaware corporation (the "US Borrower"),
Libbey Europe B.V., a company organized and existing under the laws of the
Netherlands (the "Dutch Borrower", and together with the US Borrower,
collectively the "Borrowers"), the financial institutions named therein (the
"Lenders"), The Bank of New York, as syndication agent, and Bank of America,
N.A., as administrative agent (the "Administrative Agent"), have entered into a
certain Credit Agreement dated as of the date hereof (as from time to time
amended, restated, supplemented or otherwise modified from time to time, the
"Credit Agreement"); and

      WHEREAS, the Guarantor owns, directly or indirectly, 100% of the issued
and outstanding capital stock of the US Borrower and will receive substantial
and direct benefits from the extensions of credit contemplated by the Credit
Agreement and is entering into this Guaranty to induce the Administrative Agent
and the Lenders to enter into the Credit Agreement and extend credit to the
Borrowers thereunder and to induce the other Guaranteed Creditors (as defined on
Exhibit B attached hereto) to extend Related Credit Arrangements (as defined on
Exhibit B attached hereto) to the Borrowers or any other Loan Party; and

      WHEREAS, the execution and delivery of this Guaranty is a condition
precedent to the obligation of the Lenders to extend credit to the Borrowers
pursuant to the Credit Agreement;

      NOW, THEREFORE, in consideration of the foregoing and other good and
valuable consideration contained herein, the Guarantor hereby agrees as follows:

      1.    THE GUARANTY.

            (a) The Guarantor hereby absolutely, continually, irrevocably and
unconditionally guarantees prompt, full and complete payment when due, whether
at stated maturity, upon acceleration or otherwise, and at all times thereafter,
of (i)(x) the principal of and interest on the Loans made by the Lenders to, and
any Notes held by the Lenders of, the Borrowers, or either of them as
applicable, and (y) all other amounts from time to time owing to the Lenders,
the Administrative Agent or any indemnified party by any Loan Party under the
Credit Agreement, the Notes or the other Loan Documents, including without
limitation all "Obligations" (as defined in the Credit Agreement), and (ii)
principal, interest, fees, settlement or

<PAGE>

termination values, and all other amounts from time to time owing to any
Guaranteed Creditor in respect of any Related Credit Arrangements, in each case
whether direct or indirect, absolute or contingent, now existing or hereafter
arising (collectively, the "Guaranteed Debt"). The Guarantor's obligations under
this Guaranty are collectively referred to as the "Guarantor's Obligations".
This is a guaranty of payment, not a guaranty of collection.

            (b) If there shall occur a default in payment or performance of any
of the Guaranteed Debt, whether principal, interest, premium, fee (including,
but not limited to, loan fees and attorney costs), settlement or termination
value, or otherwise, when and as the same shall become due, and after expiration
of any applicable grace period, whether according to the terms of the Credit
Agreement or any Related Credit Arrangement, by acceleration, termination or
otherwise, or upon the occurrence and during the continuance of any Event of
Default under the Credit Agreement, then the Guarantor will, upon demand thereof
by the Administrative Agent or, subject to Section 1(m) hereof, any Guaranteed
Creditor, fully pay to the Administrative Agent, for the benefit of the Lenders,
or such Guaranteed Creditor, as applicable, an amount equal to all the
applicable Guaranteed Debt then due and owing.

            (c) All payments by the Guarantor hereunder shall be paid in full,
without setoff or counterclaim or any deduction or withholding whatsoever,
including, without limitation, for any and all present and future taxes other
than Excluded Taxes. In the event that the Guarantor or any Guaranteed Creditor
is required by law to make any such non-excluded deduction or withholding (as a
result of any change after the date hereof in any requirement for a deduction or
withholding), the Guarantor agrees to pay on behalf of such Guaranteed Creditor
such amount directly to the appropriate person or entity, or if the Guarantor
cannot legally comply with the foregoing, the Guarantor shall pay to such
Guaranteed Creditor such additional amounts as will result in the receipt by
such Person of the full amount payable hereunder. The Guarantor shall be
entitled to refunds of amounts paid pursuant hereto to the extent permitted by
Section 3.01(e) of the Credit Agreement. The Guarantor shall promptly provide
such Guaranteed Creditor with evidence of payment of any such amount made on
such Person's behalf.

            (d) The Guarantor waives notice of the acceptance of this Guaranty
and of the extension or incurrence of the Guaranteed Debt or any part thereof.
The Guarantor further waives all setoffs and counterclaims and presentment,
protest, notice (other than notices specifically required in the Loan
Documents), filing of claims with a court in the event of receivership,
bankruptcy or reorganization of the Borrowers, or either of them as applicable,
demand or action on delinquency in respect of the Guaranteed Debt or any part
thereof, including any right to require any Guaranteed Creditor to sue the
Borrowers, or either of them as applicable, any other guarantor or any other
Person obligated with respect to the Guaranteed Debt or any part thereof, or
otherwise to enforce payment thereof against any collateral securing the
Guaranteed Debt or any part thereof.

      The Guarantor hereby guarantees that the Guarantor's Obligations will be
paid in Dollars (except to the extent that any Obligation is required to be paid
in euro, the Guarantor shall pay such Obligation in euro) in same day funds at
the Administrative Agent's Office, on behalf of the applicable Guaranteed
Creditor, or with respect to demands permitted to be made directly by any
Guaranteed Creditor hereunder, at the applicable office of such Guaranteed
Creditor, as the case

                                       2
<PAGE>

may be, regardless of any law, regulation or decree now or hereafter in effect
that might in any manner affect the Guaranteed Debt, or the rights of the
Guaranteed Creditors with respect thereto as against any Loan Party, or cause or
permit to be invoked any alteration in the time, amount or manner of payment by
any Loan Party of any or all of the Guaranteed Debt. Payment obligations under
this Guaranty shall not be discharged by an amount paid in any currency other
than Dollars or euro, as the case may be, whether pursuant to judgment or
otherwise. To the extent that a judgment is given in respect of any amount due
hereunder in currency other than the currency in which the obligation subject to
the judgment was originally denominated, the provisions of Section 8.04 of the
Credit Agreement shall apply.

            (e) The Guarantor hereby agrees that, to the fullest extent
permitted by law, its obligations hereunder shall be continuing, absolute and
unconditional under any and all circumstances and not subject to any reduction,
limitation, impairment, termination, defense (other than irrevocable payment in
full of the Guaranteed Debt), setoff, counterclaim or recoupment whatsoever (all
of which are hereby expressly waived by it to the fullest extent permitted by
law), whether by reason of any claim of any character whatsoever, including,
without limitation, any claim of waiver, release, surrender, alteration or
compromise. The validity and enforceability of this Guaranty shall not be
impaired or affected by any of the following to the extent permitted by law: (i)
any extension, amendment, modification or renewal of, or indulgence with respect
to, or substitution for, the Guaranteed Debt or any part thereof or any
agreement relating thereto at any time; (ii) any failure or omission to perfect
or maintain any lien on, or preserve rights to, any security or collateral or to
enforce any right, power or remedy with respect to the Guaranteed Debt or any
part thereof or any agreement relating thereto, or any collateral securing the
Guaranteed Debt or any part thereof; (iii) any waiver of any right, power or
remedy or of any default with respect to the Guaranteed Debt or any part thereof
or any agreement relating thereto or with respect to any collateral securing the
Guaranteed Debt or any part thereof; (iv) any release, surrender, compromise,
settlement, waiver, subordination or modification, with or without
consideration, of any collateral securing the Guaranteed Debt or any part
thereof, any other guaranties with respect to the Guaranteed Debt or any part
thereof, or any other obligations of any person or entity with respect to the
Guaranteed Debt or any part thereof; (v) the enforceability or validity of the
Guaranteed Debt or any part thereof or the genuineness, enforceability or
validity of any agreement relating thereto or with respect to any collateral
securing the Guaranteed Debt or any part thereof; (vi) the application of
payments received from any source (other than the Guarantor) to the payment of
indebtedness other than the Guaranteed Debt, any part thereof or amounts that
are not covered by this Guaranty even though the Guaranteed Creditors might
lawfully have elected to apply such payments to any part or all of the
Guaranteed Debt or to amounts that are not covered by this Guaranty; (vii) any
change of ownership of any Loan Party or the insolvency, bankruptcy or any other
change in the legal status of any Loan Party; (viii) any change in, or the
imposition of, any law, decree, regulation or other governmental act which does
or might impair, delay or in any way affect the validity, enforceability or the
payment when due of the Guaranteed Debt; (ix) the failure of any Loan Party to
maintain in full force, validity or effect or to obtain or renew when required
all governmental and other approvals, licenses or consents required in
connection with the Guaranteed Debt or this Guaranty, or to take any other
action required in connection with the performance of all obligations pursuant
to the Guaranteed Debt or this Guaranty; (x) the existence of any claim, setoff
or other rights which the Guarantor may have at any time against any Loan Party,
any other guarantor in connection herewith or with any unrelated transaction or

                                       3
<PAGE>

any other Person in connection herewith; (xi) the Guaranteed Creditors'
election, in any case or proceeding instituted under chapter 11 of the United
States Bankruptcy Code, of the application of Section 1111(b)(2) of the United
States Bankruptcy Code or any comparable provision applicable to the Dutch
Borrower or its assets or operations under any applicable Debtor Relief Laws;
(xii) any borrowing, use of cash collateral, or grant of a security interest by
any Loan Party as debtor in possession, under Section 363 or 364 of the United
States Bankruptcy Code or any comparable provision applicable to the Dutch
Borrower or its assets or operations under any applicable Debtor Relief Laws;
(xiii) the disallowance of all or any portion of any of the Guaranteed
Creditors' claims for repayment of the Guaranteed Debt under Section 502 or 506
of the United States Bankruptcy Code or any comparable provision applicable to
the Dutch Borrower or its assets or operations under any applicable Debtor
Relief Laws; or (xiv) any other fact or circumstance which might otherwise
constitute grounds at law or equity for the discharge or release of the
Guarantor from its obligations hereunder (other than irrevocable payment in full
of the Guaranteed Debt), in each case above, all whether or not the Guarantor
shall have had notice or knowledge of any act or omission referred to in the
foregoing clauses (i) through (xiv) of this paragraph. It is agreed that the
Guarantor's liability hereunder is independent of any other guaranties or other
similar obligations at any time in effect with respect to the Guaranteed Debt or
any part thereof and that the Guarantor's liability hereunder may be enforced
regardless of the existence, validity, enforcement or non-enforcement of any
such other guaranties or other obligations or any provision of any applicable
law or regulation purporting to prohibit payment by any Loan Party of the
Guaranteed Debt in the manner agreed upon among the Guaranteed Creditors and
such Loan Party.

            (f) Credit may be granted or continued from time to time by the
Guaranteed Creditors to the Borrowers, or either of them as applicable, without
notice to or authorization from the Guarantor regardless of any Loan Party's
financial or other condition at the time of any such grant or continuation. No
Guaranteed Creditor shall have an obligation to disclose or discuss with the
Guarantor its assessment of the financial condition of any Loan Party.

            (g) Until (but only upon) the irrevocable payment in full of the
Guaranteed Debt and the termination of all commitments of the Lenders to make
Credit Extensions and all commitments of any other Guaranteed Creditors to make
Related Credit Arrangements which could give rise to any Guaranteed Debt, (i)
the Guarantor shall have no right of subrogation, contribution or similar rights
with respect to the Guaranteed Debt, (ii) the Guarantor hereby waives any right
to enforce any remedy which any Guaranteed Creditor now has or may hereafter
have against the Borrowers, or either of them as applicable, any endorser or any
other guarantor of all or any part of the Guaranteed Debt, and (iii) the
Guarantor hereby waives any benefit of, and any right to participate in, any
security or collateral given to any Guaranteed Creditor to secure payment of the
Guaranteed Debt or any part thereof or any other liability of the Borrowers, or
either of them as applicable, to any Guaranteed Creditor. If any amounts are
paid to the Guarantor in violation of the foregoing limitation, then such
amounts shall be held in trust for the benefit of the Lenders or such other
Guaranteed Creditor, as applicable, and shall forthwith be paid by the Guarantor
to the Administrative Agent for the benefit of the Lenders or such other
Guaranteed Creditor, as applicable, for application to the Guaranteed Debt, if
any, then due and owing.

                                       4
<PAGE>

            (h) Except as specifically otherwise provided in the Loan Documents,
the Guarantor authorizes each Guaranteed Creditor to take any action or exercise
any remedy in good faith with respect to any collateral from time to time
securing the Guaranteed Debt, which the Guaranteed Creditors in their sole
discretion shall determine, without notice to the Guarantor.

            (i) In the event the Guaranteed Creditors in their sole discretion
elect to give notice of any action with respect to any collateral securing the
Guaranteed Debt or any part thereof, ten days' written notice mailed to the
Guarantor by ordinary mail at its address referred to in Section 4 shall be
deemed reasonable notice of any matters contained in such notice. The Guarantor
consents and agrees that no Guaranteed Creditor shall be under any obligation to
marshal any assets in favor of the Guarantor or against or in payment of any or
all of the Guaranteed Debt.

            (j) In the event that acceleration of the time for payment of any of
the Guaranteed Debt is stayed upon the insolvency, bankruptcy or reorganization
of any Loan Party all such amounts shall nonetheless be payable by the Guarantor
during the continuance of an Event of Default forthwith upon demand by the
Administrative Agent or such other Guaranteed Creditor. The Guarantor further
agrees that, to the extent that any Loan Party makes a payment or payments to
any of the Guaranteed Creditors on the Guaranteed Debt, or any Guaranteed
Creditor receives any proceeds of collateral or any other guaranty securing the
Guaranteed Debt, which payment or receipt of proceeds or any part thereof is
subsequently invalidated, declared to be fraudulent or preferential, set aside
or required to be returned or repaid to any Loan Party, its estate, trustee,
receiver, debtor in possession or any other party, including, without
limitation, the Guarantor, under any insolvency or bankruptcy law, state or
federal law, common law or equitable cause, then to the extent of such payment,
return or repayment, the Guaranteed Debt or part thereof which has been paid,
reduced or satisfied by such amount shall be reinstated and continued in full
force and effect as of the date when such initial payment, reduction or
satisfaction occurred as if such payment, reduction or satisfaction had never
occurred.

            (k) No delay on the part of any Guaranteed Creditor in the exercise
of any right, power or remedy shall operate as a waiver thereof, and no single
or partial exercise by any Guaranteed Creditor of any right, power or remedy
shall preclude any further exercise thereof; nor shall any amendment,
supplement, modification or waiver of any of the terms or provisions of this
Guaranty be binding upon the Guaranteed Creditors, except as set forth in
Section 10.01 of the Credit Agreement or as otherwise expressly set forth in a
writing duly signed and delivered on the Lenders' behalf by the Administrative
Agent with the consent of the Required Lenders or all of the Lenders, as the
case may be, in each case as required by Section 10.01 of the Credit Agreement.
The failure by the Guaranteed Creditors at any time or times hereafter to
require strict performance by any Loan Party of any of the provisions,
warranties, terms and conditions contained in any promissory note, pledge
agreement, security agreement, agreement, guaranty, instrument or document now
or at any time or times hereafter executed pursuant to the terms of, or in
connection with, any Guaranteed Debt by any Loan Party or the Guarantor and
delivered to any Guaranteed Creditor shall not waive, affect or diminish any
right of any Guaranteed Creditor at any time or times hereafter to demand strict
performance thereof, and such right shall not be deemed to have been waived by
any act or knowledge of the Guaranteed Creditors, their agents, officers or
employees, unless such waiver is contained in an instrument in writing duly
signed and delivered (x) with respect to the Guaranteed Debt described in
Section

                                       5
<PAGE>

1(a)(i) hereof, on the Required Lenders' behalf by the Administrative Agent and
(y) with respect to the Guaranteed Debt described in Section 1(a)(ii) hereof, by
the Guaranteed Creditor party to such Related Credit Arrangements. No waiver by
any Guaranteed Creditor of any default shall operate as a waiver of any other
default or the same default on a future occasion, and no action by any
Guaranteed Creditor permitted hereunder shall in any way affect or impair any
Guaranteed Creditor's rights or powers, or the obligations of the Guarantor
under this Guaranty. The remedies herein are cumulative and not exclusive of any
other remedies available to the Guaranteed Creditors at law or in equity. Any
determination by a court of competent jurisdiction of the amount of any
Guaranteed Debt owing by the Borrowers, or either of them as applicable, to the
Guaranteed Creditors shall be conclusive and binding on the Guarantor
irrespective of whether the Guarantor was a party to the suit or action in which
such determination was made.

            (l) Notwithstanding any reference herein to any collateral securing
any of the Guaranteed Debt, it is acknowledged that, on the date hereof, neither
the Guarantor nor any other Loan Party has granted, or has any obligation to
grant, any security interest in or other lien on any of its property as security
for the Guaranteed Debt other than such obligations as the US Borrower may have
to "Cash Collateralize" L/C Obligations as and to the extent expressly provided
in the Credit Agreement.

            (m) Notwithstanding any other provision contained in this Guaranty,
(i) until the Facility Termination Date, from and after the occurrence and
during the continuance of any Event of Default, no Guaranteed Creditor shall be
entitled, except as expressly provided in the Credit Agreement, to institute any
action to enforce any right, power or remedy hereunder against the Guarantor in
respect of Guaranteed Debt arising under the Loan Documents, except by virtue of
the enforcement of the provisions hereof by the Administrative Agent on behalf
of such Guaranteed Creditors as provided herein and in the Credit Agreement and
otherwise available under applicable Laws, (ii) each Guaranteed Creditor, by its
execution of the Credit Agreement (or an Assignment and Assumption Agreement),
or by its acceptance (whether or not as a Lender) of any benefits hereunder
(including entering into any Related Credit Arrangements in reliance on the
terms hereof) (x) agrees (1) that it shall not have, prior to the Facility
Termination Date, any right to notice of any action or to consent to, direct or
object to any action hereunder or under any other Loan Document or otherwise in
respect of the Guarantor's Obligations relating to Guaranteed Debt described in
Section 1(a)(i) hereof (including the release or modification of the Guarantor's
Obligations or security therefor) other than in any capacity it may have as a
Lender and only to the extent expressly provided in the Loan Documents, and (2)
that any action it may take or fail to take as a Guaranteed Creditor in respect
of Guaranteed Debt described in Section 1(a)(ii) hereof shall not impair or
otherwise affect the rights, powers and privileges of the Administrative Agent
or any other Guaranteed Creditor to enforce the terms hereof and of the other
Loan Documents in respect of all other Guaranteed Debt, and (y) acknowledges and
accepts the appointment of the Administrative Agent pursuant to the terms of the
Credit Agreement, and that with respect to the actions and omissions of the
Administrative Agent hereunder or otherwise relating hereto that do or may
affect such Guaranteed Creditor (including without limitation at all times after
the occurrence of the Facility Termination Date if at any such time it then
remains a Guaranteed Creditor), the Administrative Agent and its Related Parties
shall be entitled to all the rights, benefits and immunities conferred under
Article IX of the Credit Agreement, and (iii) following the occurrence of the
Facility Termination Date, the provisions of this Guaranty shall be deemed to
run severally to and for the benefit of each

                                       6
<PAGE>

remaining Guaranteed Creditor, with the effect and to the same extent as if the
Guarantor had entered into this Guaranty separately with each such remaining
Guaranteed Creditor, such that (x) the terms hereof may be modified by and
between the Guarantor and any such Guaranteed Creditor without affecting the
terms hereof as may then be in effect as between the Guarantor and any other
Guaranteed Creditor, (y) no action, omission or other event or circumstance
arising between or affecting the relative rights and duties of the Guarantor and
any such Guaranteed Creditor shall affect the relative rights and duties of the
Guarantor and any other Guaranteed Creditor, and (z) each remaining Guaranteed
Creditor shall have the right, power and authority to enforce the terms hereof
for its benefit in its own name in such manner as may be permitted by the terms
hereof or otherwise by applicable Laws. For purposes hereof, "Facility
Termination Date" means the date as of which all of the following shall have
occurred: (A) the Borrowers shall have permanently terminated the credit
facilities under the Loan Documents by final payment in full of all Outstanding
Amounts, together with all accrued and unpaid interest and fees thereon, other
than (i) the undrawn portion of Letters of Credit and (ii) all letter of credit
fees relating thereto accruing after such date (which fees shall be payable
solely for the account of the L/C Issuer and shall be computed (based on
interest rates and the Applicable Rate then in effect) on such undrawn amounts
to the respective expiry dates of the Letters of Credit), in each case as have
been fully Cash Collateralized, or as to which other arrangements with respect
thereto satisfactory to the Administrative Agent and the L/C Issuer shall have
been made; (B) all Commitments shall have terminated or expired; and (C) the
Borrowers and each other Loan Party shall have fully, finally and irrevocably
paid and satisfied in full all of their respective obligations and liabilities
arising under the Loan Documents (except for future obligations consisting of
continuing indemnities and other contingent Obligations of the Borrowers or any
Loan Party that may be owing to any Person pursuant to the Loan Documents and
expressly survive termination of the Credit Agreement or any other Loan
Document). The Guarantor acknowledges and agrees to the forgoing provisions of
this Section 1(m).

      2.    REPRESENTATIONS AND WARRANTIES.

      The Guarantor hereby represents and warrants to the Administrative Agent,
the Lenders and the other Guaranteed Creditors that:

Obligation to which the Guarantor is a party or any order, injunction, writ or
decree of any Governmental Authority to which the Guarantor or its property is
subject, except as would not have a Material Adverse Effect, or (iii) violate
any Law, except as would not have a Material Adverse Effect.

            (c) Governmental Authorization. No approval, consent, exemption,

            (d) Binding Effect. This Guaranty has been duly executed and

            Restricted Payments permitted pursuant to Section (3)(b)(v) below;

                  (v) the Guarantor may make one or more Restricted Payments at
            the times and to the extent that the US Borrower could make a
            Restricted Payment in the same aggregate amount pursuant to Section
            7.07 of the Credit Agreement; provided that the amount of a
            Restricted Payment made by Holdings with the proceeds of a
            Restricted Payment made to Holdings by the US Borrower shall not
            count (a second time) against the basket set forth in Section
            7.07(d) of the Credit Agreement;

                  (vi) the Guarantor may enter into transactions with the US
            Borrower to the same extent as the US Borrower is permitted to enter
            into transactions with the Guarantor as contemplated by Section 7.10
            of the Credit Agreement; and

                  (vii) the Guarantor may create, incur and permit to exist
            Guaranty Obligations of the Guarantor consisting of a guarantee by
            the Guarantor of obligations of a Restricted Subsidiary or of the US
            Borrower under any agreement not otherwise prohibited by the Credit
            Agreement.

In applying the provisions of the Credit Agreement with respect to the Guarantor
pursuant to this Section 3, except as set forth above those provisions shall be
applied, mutatis mutandis, to the Guarantor as if it were the US Borrower. For
example, notwithstanding the fact that the term "Acquisition" contemplates
ownership of the acquired business only by the US Borrower or a Restricted
Subsidiary, the Guarantor would be permitted, by virtue of Section 7.02(i) of
the Credit Agreement, to make an Acquisition which results in the Guarantor
owning the acquired business if the US Borrower would be permitted pursuant to
such Section 7.02(i) of the Credit Agreement to make the same Acquisition for
the US Borrower's own account. Similarly, the Guarantor may make a Restricted
Payment to one or more of its stockholders if the US Borrower

                                       9
<PAGE>

could make a Restricted Payment in the same amount at such time to its
stockholder, the Guarantor.

            (c) Notwithstanding anything in the foregoing clause b to the
contrary, the aggregate amount of Indebtedness in respect of money borrowed
(other than such Indebtedness permitted pursuant to Section 3(b)(ii)(A) above)
of the Guarantor at any one time outstanding shall not exceed an amount equal to
the sum of (i) the aggregate principal amount of Indebtedness or guaranties
thereof of the Guarantor currently outstanding, and any refinancings thereof,
(ii) the aggregate principal amount not to exceed $35,000,000 of (A) any
incremental increases in the US Borrower's Senior Notes issued pursuant to a
certain Note Purchase Agreement and any guaranties thereof to which the US
Borrower is a party dated as of March 31, 2003 and (B) the private placement of
Indebtedness and any guaranties thereof having scheduled maturity greater than
five years of any Foreign Subsidiary that is a Restricted Subsidiary permitted
under the Credit Agreement, and, in the case of (ii)(A) and (B) above, any
replacements or refinancings thereof, including any increases thereof up to the
$35,000,000 limit and (iii) $50,000,000.

            (d) Except as specifically set forth in clause (b)(v), all actions
taken by the Guarantor in reliance upon a basket set forth in any section of
Article VII of the Credit Agreement shall reduce dollar-for-dollar the amount of
such basket remaining available to the US Borrower and its Restricted
Subsidiaries for purposes of such Section, as if the US Borrower had taken such
action; and all actions taken by the US Borrower or a Restricted Subsidiary in
reliance upon a basket set forth in any section of Article VII of the Credit
Agreement shall reduce dollar-for-dollar the amount of such basket remaining
available to the Guarantor for purposes of such Section as incorporated herein.
The Guarantor shall not permit the US Borrower or any of the US Borrower's
Restricted Subsidiaries to take any action in reliance upon a basket set forth
in any section of Article VII of the Credit Agreement to the extent that, after
giving effect to such utilization of such basket by the US Borrower or such
Restricted Subsidiaries, as the case may be, the aggregate utilization of such
basket at such time by the Guarantor, the US Borrower and the US Borrower's
Restricted Subsidiaries would exceed the amount of such basket stated in the
Credit Agreement.

            (e) Notwithstanding anything herein or in the Credit Agreement to
the contrary, the Guarantor shall not create, incur or assume any Lien upon
stock of the US Borrower owned by it other than Liens of the type described in
Sections 7.01(a), (c) or (h) of the Credit Agreement.

      4.    MISCELLANEOUS.

            (a) Subject to the provisions of Section 1(j), this Guaranty shall
continue in effect (i) as to the Administrative Agent and the Lenders, until the
Credit Agreement and all other commitments of the Lenders to make Credit
Extensions which could give rise to Guaranteed Debt described in Section 1(a)(i)
have terminated and such Guaranteed Debt and all other amounts payable hereunder
have been paid in full and (ii) as to any other Guaranteed Creditors, until all
Related Credit Arrangements which could give rise to Guaranteed Debt have been
fully or finally satisfied or other arrangements satisfactory to the respective
parties to each such Related Credit Arrangement have been made in lieu of the
continuation of this Guaranty.

                                       10

            (b) The Guarantor confirms and ratifies Section 10.08 of the Credit
Agreement and agrees that the Lenders shall have, relative to the Guarantor, the
set-off rights provided therein. In addition to any rights and remedies of the
Administrative Agent and the Lenders provided by law, upon the occurrence and
during the continuance of any Event of Default, the Administrative Agent and
each Lender is authorized at any time and from time to time, without prior
notice to the Guarantor, any such notice being waived by the Guarantor to the
fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final (but not trust
accounts)) at any time held by, and other indebtedness at any time owing by,
such Lender to or for the credit or the account of the Guarantor against any and
all Guaranteed Debt then due and owing to such Lender, now or hereafter
existing, irrespective of whether or not the Administrative Agent or such Lender
shall have made demand under this Guaranty or any other Loan Document. Each
Lender agrees promptly to notify the Guarantor and the Administrative Agent
after any such set-off and application made by such Lender; provided, however,
that the failure to give such notice shall not affect the validity of such
set-off and application.

            (c) The Guarantor agrees to pay all reasonable costs, fees and
out-of-pocket expenses (including reasonable attorney costs of the
Administrative Agent, any Lender or any other Guaranteed Creditor) incurred by
the Administrative Agent, any Lender or any Guaranteed Creditor in collecting or
enforcing the obligations of the Guarantor under this Guaranty.

            (d) This Guaranty shall bind the Guarantor and its successors and
assigns and shall inure to the benefit of the Guaranteed Creditors and their
successors and assigns permitted pursuant to Section 10.06 of the Credit
Agreement. All references herein to the Borrowers, or either of them as
applicable, shall be deemed to include its successors and assigns including,
without limitation, a receiver, trustee or debtor in possession of or for the
Borrowers, or either of them as applicable.

            (e) THIS GUARANTY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE
WITH, THE LAW OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE
PERFORMED ENTIRELY WITHIN SUCH STATE; PROVIDED THAT EACH Guaranteed CreditoR AND
THE GUARANTOR SHALL RETAIN ALL RIGHTS ARISING UNDER FEDERAL LAW.

            (f) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS GUARANTY MAY
BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK SITTING IN NEW YORK OR OF THE
UNITED STATES FOR THE SOUTHERN DISTRICT OF SUCH STATE, AND BY EXECUTION AND
DELIVERY OF THIS AGREEMENT, THE GUARANTOR CONSENTS, FOR ITSELF AND IN RESPECT OF
ITS PROPERTY, TO THE NON-EXCLUSIVE JURISDICTION OF THOSE COURTS. THE GUARANTOR
IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING ANY OBJECTION TO THE LAYING OF VENUE
OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER
HAVE TO THE BRINGING OF ANY ACTION OR PROCEEDING 1N SUCH JURISDICTION IN RESPECT
OF THIS GUARANTY. THE GUARANTOR WAIVES PERSONAL SERVICE OF ANY SUMMONS,
COMPLAINT OR OTHER PROCESS, WHICH MAY BE MADE BY ANY OTHER MEANS PERMITTED BY
THE LAW OF SUCH STATE.

            (g) THE GUARANTOR HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY
OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION ARISING HEREUNDER OR IN ANY WAY
CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE GUARANTOR, THE
ADMINISTRATIVE AGENT OR THE LENDERS OR ANY OF THEM WITH RESPECT TO ANY LOAN
DOCUMENT, OR THE TRANSACTIONS RELATED THERETO, IN EACH CASE WHETHER NOW EXISTING
OR HEREAFTER ARISING, AND WHETHER FOUNDED IN CONTRACT OR TORT OR OTHERWISE; AND
THE GUARANTOR HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR
CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY, AND THAT THE
ADMINISTRATIVE AGENT OR ANY LENDER MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF
THIS SECTION WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE GUARANTOR
TO THE WAIVER OF ITS RIGHT TO TRIAL BY JURY.

            (h) Wherever possible, each provision of this Guaranty shall be
interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this Guaranty shall be prohibited by or invalid under
such law, such provision shall be ineffective to the extent of such prohibition
or invalidity without invalidating the remainder of such provision or the
remaining provisions of this Guaranty.

            (i) Except as otherwise expressly provided herein, any notice
required or desired to be served, given or delivered to any party hereto under
this Guaranty shall be given in the manner and with the effect set forth in
Section 10.02(a) of the Credit Agreement. The notice address for the Guarantor
